The specific embodiment
See also Fig. 1 to Fig. 3, the utility model batteries of electric automobile pouring-basket cooling system is used for when power brick is charged it being cooled off, and this power brick cooling system comprises cold air supply unit, power brick and interchange of heat gas output unit in cold-air device refrigerating cycle unit, the car.This cold-air device refrigerating cycle unit and Che Nei cold air supply unit are existing structure, and it constitutes the on-board air conditioner cooling system of existing electronlmobil.
This cold-air device refrigerating cycle unit comprises condenser 1, liquid storage pipeline 2, expansion valve 4, high-pressure channel 5, on-board air conditioner compressor 11, air conditioner motor 12 and evaporator 13.This on-board air conditioner compressor 11 and air conditioner motor 12 link together, and it can reach compressed-air actuated purpose.The on-board air conditioner compressor 11 of this connection one and compression motor 12 are placed on the front cross rail place of electronlmobil and adjacent with condenser 1.This condenser 1 and evaporator 13 couple together by pressure piping 5, and the midway location of this pressure piping 5 is provided with expansion valve 4.This evaporator 13 couples together by pipeline 3 with on-board air conditioner compressor 11.
The cold air supply unit comprises extraneous air import 6, air filtration import 7, blowing engine 8, distribution box 9 and air outlet 10 in this car, and this blowing engine 8, distribution box 9, air outlet 10 and evaporator 13 enclose near the side before being positioned at electronlmobil.
Before the power brick charging, open this on-board air conditioner cooling system, a few minutes the temperature of after cooling air will reach the cooling requirement.Power brick when charging, close the various air outlets of this on-board air conditioner cooling system and have only air outlet 10 work, thus but the increase cooling performance of maximum possible.
This power brick 18 is an existing structure, its inside is provided with a plurality of battery pack 17 and hot switching path 16, the two ends of this hot switching path 16 are respectively cold air import 15 and exchange gas outlet 19, and this cold air import 15 is communicated with the air outlet 10 of cold air supply unit in the car by circulation duct.The cold air of on-board air conditioner cooling system is flowed in the power brick 18 by cold air import 15 through circulation duct from air outlet 10, and air-flow is distributed in the power brick 18 after baffle plate is regulated, and mainly concentrates in the hot switching path 16.When high-voltage charging, battery pack produces a large amount of heats, and mainly the lug via battery distributes.When cold airflow was crossed lug, owing to existing the temperature difference to produce interchange of heat, the heat of exchange was taken away from exchange gas outlet 19 by cold airflow and is flowed out, and the lug place temperature difference decreases.Through continuous interchange of heat, because the heat of the taking away heat that lug produces during greater than charging so the reduction slowly of the temperature of lug finally reaches an equilibrium temperature, thereby reaches the electrically-charged purpose of cooling.
